So far I have only seen 8800GTX vs 7900GTX or 8800GTX vs 8800GTX SLI.

I am trying to find a test between 7900GTX SLI vs 8800GTX SLI.

Anyone know any?

I am trying to decide if it's worth for me to upgrade. I bought 2x7900GTX less than a year ago and ironically I have already seen several games that cannot deliver +60fps in SLI mode. :(

Well ONE 8800GTX is faster than 2x7900GTX in most cases. So 2x8800GTXs should be A LOT faster than 2x7900GTXs.

I haven't seen any SLI vs SLI tests. But here is a 7900GTX sli vs one 8800GTX.

Very Impressive.

Here is an article which has 7900GTX SLI vs 8800GTX SLI

Well i have a 7800GTX SLi and 1 8800GTX and never noticed much diffrence with SLi enabled games but if there is no profile there is a big diffrence.

here is mine, and also note that all the hardware are at there stock clocks

but thats with WinXP theme on, McAfee, media source running, so thats a lot of programs running

my specs of my rig are in my sig, but I know have 8800 GTX's in SLi and im selling both my 7900 GTX's, they have never been OC, maybe 3 times via ntune

Mine runs at 9089pts and thats with a single 8800GTX with the cpu @ 2.66GHz.

Their numbers are off. Here is the result for my 8800GTS (single card) @ the same settings as their 3DMark06 test (1600x1200, 4xAA, 8xAF):

http://service.futuremark.com/compare?3dm06=673763

I almost got double their score for a single 8800GTS. Infact, I almost got double their score for 7900GTX SLi. And as you can see my processor is far from being high end.

Something is definitely wrong with that benchmark.

--EDIT--

Looks like I might have forgotten to disable SLi. I'll rebench my card tonight when I get in from work (1:30 AM). I'll post my results then.

Here is mine, only the CPU is overclocked.

Okay, I did disable SLi completely this time- but my results are still (practically) the same.

http://service.futuremark.com/compare?3dm06=674658

I'm not sure what they were doing wrong with their setup in that review from tom's hardware- but obviosly they were way off.

As such, a single 8800GTX should score quite a bit better.

Oh, and comparing my results with a single 8800GTS to that of Dazz's results with his single 8800GTX- it is quite obvious that my CPU is the main bottleneck. If I am recalling correctly, the 8800GTS (single) should score around 7-8K in 3DMark06. But- my CPU didn't even manage a half a frame a second for an average in any of the CPU tests. While Dazz's should have average over 1 frame per second. Thus the huge difference in our scores (atleast, this is the only explanation I can come up with).

I will be getting the rest of my hardware for my new build tomorrow, and I should have it fully assembled come Thursday. As such, I'll post some new benchmarks with just one and then both of my 8800GTS's. Hopefully (and more than likely) the faster CPU in my new rig will make a significant difference. ;)

I did notice when i clicked on you link you had 4x FSAA enabled & AF 8x + @ 1600x1200 It says customer benchmark on yours.

I have benchmarked the hell out my cards.

That is because I was comparing my results to that of the one's Tom got in that review that somebody (I believe it was Crainger) linked to.

Here are my results are 1920x1440 with 16xAA and 16xAF via the DCP. The dramatic increase in both the resolution and AA/AF upped my score actually. ;)

http://service.futuremark.com/compare?3dm06=661981

Granted, in that test I did have SLi enabled. Below is my results at 1920x1440, 16xAA, 16xAF via the DCP and with SLi disabled:

http://service.futuremark.com/compare?3dm06=674820

If you compare that ^^^ test with the one I ran @ 1600x1200, 4xAA, 8xAF- I only lost about 100 points. :p

I believe that my scores are so low mostly due to my processor, but also due to the drivers.

I have some thoughts about this deal.

I run games in the highest resolution possible, 1920x1440 when I can. That looks best on my 22" monitor.

Two 8800GTX will cost me 13000 Swedish Krona.
It seems 7900GTX go for 3500-4200 Swedish Krona on the swedish 2nd hand market.
This means that if I act now I will not pay more than 6000 for new cards, which I can afford right now.

However, on the other hand I wonder if I need them. I have completed the big boys this year, Oblivion, Gothic 3, NWN2... The new supertitles wont pop up until into the next year, post Vista, and then there might be another Nvidia update by then. If I grab theese babies now they will already be outdated once the new games (Crysis/AlanWake?) comes.

Also I have a 4800+ with 2gb 2-2-2-5 DDR. I do not know how long that will last or if that rig is already outdated.

Here's my current score (I did not bother about changing my desktop for this... My desktop is in 2048x1536 and I run alot of software drivers, deamon tools, antivirus etc in the background, and nothing on my righ is overclocked):

I'm wondering if something is seriously wrong with my setup. My 8800GTS (single) should atleast match your score. Is this CPU holding me back that badly?

Dad-gummit! This cements my idea to upgrade my cpu, mobo, and ram come March. :D

My 2 7800GTX does 7990 http://service.futuremark.com/compare?3dm06=229042 Just run your benchmarks at defualt like us and see the diffrence i don't have registered version to do it, well i do with the ASUS card but when i upload the resualt it says i am using an illegal key WTF? Asus has a bundling partnership with them.

I do not know what is to be expected by two overclocked 7900GTX vs one 8800GTS. I havnt been updated on the 8xxx series due to my recent purchase (which I now have to update :thumbdwn: )

I Have 2 overclocked 7800GTX card and the diffrence an't all that amazing, however in games don't have decent SLi profiles if any at all there is more then twice the diffrence. But as it stands my 8800GTX is about 10% faster then 2 7800GTX overclocked cards.

At default settins I get just under 6K. :(

Not sure what is up. Maybe my CPU is just that big of a bottleneck. Currently I am using an A64 3400 (s754). It is at stock (2.4Ghz) as it doesn't oc very well at all (and I am familiar with OC'ing).

I am liking the idea of jumping to the C2 a whole lot right about now.

Then again games like Oblivion that are shader intense the difference is dramatic...In that game I get on average 3 times the performance I had with my 7900GTs in SLI when multiple NPCs are on screen or in foliage dense areas.

Really? Because I think being able to run any game with 16xAA/16xAF at a playable framerate is a huge difference... hell I could barely run Dark Messiah before on my 7800GTX SLi rig at my native resolution but now I rock it.
